The losers at Reykjavik were the people of the United States and the Soviet Union. The true protagonists at the summit were not Reagan and Gorbachev but you and me and the people of the world, and the issue was not which country would "win" the negotiations but whether the human race could survive on a planet loaded with enough nuclear bombs to destroy more than a million Hiroshimas.
Reykjavik offered an opportunity for a significant achievement in nuclear arms reduction, and the chief obstacle to success was Reagan's insistance on Star Wars. This insistance shows that Reagan and his advisers are still committed to security through military and technological means, an outdated mode of thinking in the age of the nuclear bomb.
Our President endows Star Wars with a sanctimonious quality. He seems to regard our development of a space-based missile defense system as a moral imperative, one that the Soviets are trying to frustrate. This posture of virtue only serves to obscure the true aspects of Star Wars.
Star Wars would intensify the arms race. It would militarize space, filling the heavens with a hazardous network of nuclear-driven devices, would-be Chernobyls in the sky. Its cost would be tremendous. It would be subject to a variety of relatively simple countermeasures.
